  • a double-acting hydraulic cylinder 35 and piston rod 36 is arranged in the front frame portion 1 and pivotally connected to the from frame portion and at 37 to a lug on the segment member 40 of the right-hand pair of cutter heads. The machine is fed forward during the initial cutting operation shown in FIG.
  • the double-acting hydraulic cylinder 35 and piston rod 36 swings the pair of cutter heads 21, 22 through an angle which is in excess of so much that the cutter heads get an effective start in cutting into the sidewall of the tunnel and produce an overlap of the longitudinal center line of the tunnel thereby producing a tunnel profile with a substantially flat floor and roof and slightly curved sidewalls, each cutter producing a cavity which has substantially the shape of a sector of a big cheese with flat top and bottom.
  • the upward and downward incline of the cutter axes provides better space around the cutter heads and for the roof and floor engaging shoes.
  • the rear frame portion 2 of the tunneling machine shown in FlGS. 1-3 consists of an upper deck 41 and a lower deck 42 which are connected by columns 43 and 44 which at their bottom and top ends carry wall engaging shoes 45, 46, 47, 48, respectively.
  • the shoes 46, 48 are fitted on piston rods movable in the columns 43, 44 so as to form jacks for holding the rear frame portion 2 in fixed position in a tunnel when the wall engaging shoes 45-48 are pressed against the floor and roof of the tunnel.
  • the shoes 45, 47 are universally pivoted to the columns 43, 44, respectively.
  • the rear frame portion 2 is provided with wall engaging members or shoes 53, 54 for engaging the sidewalls of the tunnel and fitted on piston rods 55, 56 of hydraulic cylinders 57, 58.

  • the frame portion 1 has a rearwardly extending beam 64 which carries a drivers compartment 49 with an operator's seat 50 and a maneuvering panel 51 with control levers 52 for controlling the operation of the cutter heads and the various hydraulic cylinders and other machinery in the tunneling machine.
  • the material of the tunnel walls removed by the cutters 39 and members 29 is transported towards the center portion of the front frame portion by the action of the cutters 39 and members 29 which operate as gathering members for the debris.
  • the cutters rotate as indicated by the arrows and the cutter heads swing towards the center line of the machine on the working strokes.
  • the debris is collected in the center portion of the machine and transported towards the rear end of the machine by means of a scraper conveyor 60 which extends around the lower decks of the machine and is driven by a motor 61.
  • the conveyor is attached to the front frame portion 1.
  • 62 is a direction indicator board which helps the operator to steer the machine in such a manner that a desired tunnel direction is obtained.
  • a laser is provided on the tunnel wall behind the machine and produces an illuminated point on the indicator board 62.
  • the machine starts cutting substantially with the cutter heads in the position illustrated in FIG. 3.
  • the cutter heads are in the swing back position of FIG. 3 and the cutters rotate.
  • the shoes of the front frame portion are under nongripping oil pressure and the frame portion 1 is advanced a distance 65 corresponding to the feed. This is the position reached in FIG. 3.
  • the gripping shoes of the front frame portion are then pressed to grip the walls and fix the frame portion in the tunnel.
  • the swinging of the cutter heads by 35, 36 is initiated and the teeth of the cutters cut a kerf in the tunnel wall material and the remaining wall portions left at the back of the cutter teeth are broken away by the conical surfaces 66 and by the members 29 or otherwise.
  • This mode of operation is very well known for instance from the Wohlmeyer US. Pat. No.
  • left-hand and right-hand cutters must be synchronized so as not to interfere with each other near the center line of the machine, and for this purpose the swinging of one pair is delayed slightly when the cutter approaches the center line with respect to the other pair in their swinging action.
  • the gripping shoes of the front frame portion are brought into nongripping or sliding position, whereas the gripping shoes of the rear frame portion are kept in gripping position.
  • the machine is then operated as above described for making a feed cut, but the cylinders 3, 6 are expanded less than the cylinders 4, during the feed cut.
  • the swing and cut operation as above described is then carried out, and after swinging back the cutter heads a new feed cut is made as just described.
  • the above operations may be repeated until the desired turn of the machine has been achieved. For making a right turn the feed cut of the right-hand cutters is reduced. For dumping the feed cut of the bottom cutters are reduced and for raising the feed cut of the roof cutters are reduced.
  • Steering of the machine may also be accomplished by bringing one the shoes l6, 17 or 30 in gripping position, producing a reduced feed cut or a negative feed with one pair of cutters and a full feed cut with the other pair and thereafter making a swinging cut with both pairs. This procedure may be repeated as many times as the geometrical form of the machine permits.
  • the arrangement of the machine provides a great variety of possibilities for steering of the machine in various directions by manipulating the cylinders 3-6 and the gripping shoes in various ways.
  • Changing the direction to a more downward direction may, for instance, be produced by disengaging the gripping shoes of the front frame portion 1, locking the hydraulic cylinders 5, 6 and expanding the cylinders 3, 4 and simultaneously making a feed cut.
  • the front frame portion is then fixed and a swinging cut is made and the steps are repeated as many times as desired.
  • the machine may be made to rise by locking the cylinders 3, 4 and expanding the cylinders 5, 6 and simultaneously making a feed cut etcetera.
  • the debris produced by the tunneling machine is gathered centrally on the conveyor 60 by the cutter heads and cutters and scraped by the conveyor 60 to the discharge chute 63 which leads to a conveyor or transportation means (not illustrated) for transporting the debris towards the tunnel opening.
  • FIGS. 4-9 the cutter heads are designated with the same numeral as the cutter head 21 in FIGS. 1-3, the equivalent frame portions are similarly designated 1 and 2 for the front and rear frame portions, respectively, the sidewall engaging shoes are all designated 32 on the front frame portion and 53 on the rear frame portion, since they fill the same functions as the corresponding shoes in FIGS. 1-3.
  • the roof and floor engaging shoes are similarly designated 30 when on the front frame portion and 46 when on the rear frame portion, and the chute for delivering debris to the out-transportation means is designated 63 as in FIG. 1.
